Solving climate change is not an overwhelming problem—it’s a 2% problem. According to Harvard Professor James McCarthy, if we reduce greenhouse gas emissions by 2% per year, we will effectively respond to the challenge of climate change.
We spoke with Dr. McCarthy about What We Know, a report he wrote with a distinguished group of scientists that helps the general public understand what we need to know about climate change. He notes that there is much we can do to slow our greenhouse gas emissions, and many cities and states have already implemented innovative solutions that previously seemed unimaginable—for example, more than 20% of Iowa’s electricity comes from wind.
Watch this video to understand:
- How we can take steps to mitigate the effects of climate change.
- How utilities, cities, and states are taking action now that will meet the challenge of climate change.
- How actions that reduce our greenhouse gas emissions also have many other benefits, such as better air quality.
